WILLIAM GEORGE SQUARES DE CART ERET, OF BEER, ENGLAND.

LAMP-HOLDER.

To all whom it may concern Be it known that I, WVILLIAM GEORGE S UAnEs on CARTERET, of The Pines, Beer, Devonshire, England, and temporarily residing at 99 South Park, Halifax, Canada, and a subject of the King of Great Britain, have invented certain new and useful Improvements in Lamp-Holders; and I. do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to devices for holding lamps or beacons upon buoys or the like to prevent swinging of the lamps and it has for its object to provide a new and improved holder and one which can be readily attached to or detached from the lamp. For full comprehension, however, of my invention reference must be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate the same parts and wherein;

Figure 1 is a front elevation of my improved holder in use; and Fig. 2 is a detail section on line 22 Fig. 1.

In the drawings Z) indicates a standard which may constitute part of a buoy or ship and has a cross-piece 0 from which a lamp d is suspended by a hook 6.

My invention relates particularly to a device for holding the lamp in position and preventing it swinging and this holding device consists of one or more hooks 7 passed loosely through a suitably fixed part such as a cross-piece g which is attached to the standard Z) a distance below the cross-piece c and formed with holes 9 for the hooks. In the preferred construction a pair of hooks are employed for each lamp, the shanks h of the hooks extending downwardly from the cross-piece and having their lower ends connected by a bar 2', such lower ends being screw-threaded and having nuts j screwed thereon and between which the bar is clamped so that when the bar is moved the hooks move with it. Coiled springs Z? encircle the shanks h and bear between the top surface of the bar i and the underside of the cross-piece g, such springs exerting their influence upon the bar '1; and through the latter drawing the hooks f down and yieldingly holding the latter against upward move ment, the downward movement of the hooks being limited by shoulders m formed upon the shank it above the cross-piece g and adapted to engage with the top of the latter.

Specification of Letters Patent.

Application filed May 3, 1913.

Serial No. 765,279.

\Vashers or wear plates 2 are provided betweenthe ends of the springs and the crosspiece 9 and bar 2", respectively, the washers being reduced as at 3 for the accommodation of the springs. When the cross-piece g is formed of wood or other material similarly affected by dampness, it is liable to contract upon the shanks h and interfere with the free up and down movement of the hooks so to prevent this I have located metallic bushings l in the holes 9 which constantly provide a loose passage for the free movement of the shanks 7L therethrough.

. The hooks f are adapted to engage with the lamp and to secure this engagement any suitable device may he formed upon the lamp but I prefer to provide a stud n upon each side of the latter, the hooks being so disposed along the cross-piece 9 that they are just beneath these studs when the lamp is suspended from the hook 6. By moving the bar 13 up the hooks are brought to a position where the lamp can be swung slightly to bring the studs beneath the hooks and by releasing the bar such hooks will be forced down by the springs in into engagement with the studs, the tension of the springs securely maintaining the engagement of the hooks with the studs and rigidly holding the lamp in position to prevent swinging of the latter in rough weather. The lamp can be readily released by moving the bar 2' up to raise the hooks and permit of the studs swinging clear of the same. The hooks may be used separately and in this case the bar 2' is dispensed with and the spring 70 attached to the lower end of the shank h to enable the hook to be independently operated.

What I claim is as follows:

1. In a device of the character described, the combination with a lamp and means for supporting the same, of a device, independent of the supporting means, to prevent swinging of the lamp, such device including a fixed part, a hook passed loosely through the fixed part and adaptedv to engage with the lamp and a spring for yieldingly holding the hook against upward movement.

2. In a device of the character described, the combination with a lamp and means for supporting the same, of a device, independent of the supporting means, to prevent swinging of the lamp, such device including a fixed part below the lamp, a hook passed loosely through the fixed part and adapted to engage wit-h the lamp and a spring attached to the lower end of the hook and bearing against the underside of the fixed part. 7

3. In a device of the character described,

the combination with a fixed part, of a lamp suspended above the fixed part, studs presented by the lamp, hooks passed loosely through the fixed part and adapted to engage with the said studs, a bar attached to and connectingthe lower ends of the hooks, springs encircling each of the hooks and gearing between the fixed part and the said e. In a device of the character described, the combination with a fixed part, of a lamp suspended above the fixed part, studs presented by the lamp, hooks passed loosely through the fixed part and adapted toengage with the said studs, shoulders upon the hooks and adapted to engage with the top of the fixed part, a bar attached to and connecting the lower ends of the hooks, springs encircling each of the hooks and bearing between the fixed part and the said bar.

said shanks at a point above the fixed part, a

bar connecting the lower ends of the shanks, nuts upon the shanks and clamping the bar between them, springs encircling each of the hooks and bearing between the fixed part and the bar, and wear plates between the springs and the fixed part and connecting bar, respectively.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
